The Lowdown
Alright folks, Rusty here. Let's have a look at what Jaconé’s got cooking for us over the next couple of weeks.
We’re starting off with a solid run of surf, but it's not for the faint of heart. The first few days are pumping with some serious size, so leave the foamies at home.
Sunday morning, the 23rd, we’re looking at a clean 6 foot swell from the SSW, with a light cross-off breeze keeping things tidy. The water is sitting at 73°, which is pretty much normal for this time of year. The energy is solid, reading 655, so there’s plenty of push.
Monday the 24th is where things get heavy. The morning session sees a 8 foot S swell, and the energy jumps right up to 2077 – that’s a lot of power. By the afternoon, it’s even bigger, hitting 10 feet from the S with a long 14-second period. The energy is a massive 3200. That’s expert territory only, and honestly, it might be too much even for this exposed spot. The wind is light and cross-off, so it’ll be clean, but you’d better know what you’re doing.
Tuesday the 25th drops back slightly to 8 feet in the morning and 8 feet in the afternoon, but the wind picks up a touch, making it a bit more challenging. The energy is still high, 2698 in the morning, so it’s not a day to be casual.
Wednesday the 26th is still solid. The morning has a clean 6 feet from the S with a 12-second period, and the energy is 2125. The afternoon bumps up to 8 feet with a very long 15-second period, and the energy goes to 2960. That long period means the sets will be powerful and lined up, perfect for a point break, but at a beach break it might be a bit top-to-bottom.
Now, Thursday the 27th is the standout. The morning has a 8 foot S swell, a 14-second period, and the wind turns offshore from the NE at 12 mph. The energy is 2162, and the report says ‘excellent surf conditions’. The afternoon is even better: 7 feet with a light offshore, all clean. This is the best quality window of the whole run.
Friday the 28th is a beauty for the morning session. Glassy conditions with NNE wind at 3 mph, and a clean 4 foot S swell. The energy is 606, and it’s going to be perfect for a longboard or a funboard. The crowds are possible here, but on a morning like that, it’s worth the company.
The next few days drop in size and energy. Saturday the 29th is small, around 4 feet, and Sunday the 30th has a morning spike of 6 feet from the ENE with a clean offshore wind, but the energy is only 718. The real gem is Monday the 31st morning: glassy calm, 7 feet from the ENE, and 863 energy. That’s a great dawn patrol session.
After that, we hit a rough patch. From Tuesday, September 1st, through the end of the week, the wind is rubbish – onshore or cross-onshore – and the waves are messy. There’s a moment on Thursday the 3rd afternoon where the wind goes glassy and the swell is 8 feet from the SSW with a 11-second period, but the energy is 1176. That’s a good window for experienced surfers, but you have to sit through a lot of junk to get to it.
Saturday the 5th and Sunday the 6th are a mixed bag. Sunday morning the 6th looks promising again with a clean 6 feet from the SSE and a light offshore, but it’s a long way out. The last solid day in the window is Monday the 7th, with a clean 4 feet from the SE.
Overall, the best bet is the 27th for the best quality, and the 28th for the cleanest fun waves. The early week from the 24th to the 26th is for the big-wave crew only.
Rusty out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
